It also includes phase failure detection, so if you lose a phase, this breaker will drop the load before the motor cooks. This breaker is rated for a voltage range of 20 to 690 V and offers a 100 kA breaking capacity at both 240 V and 400 V AC, which means it can safely interrupt a short-circuit fault up to that level without welding its contacts or blowing apart. At 480 V, the rated current is 0.63 A; at 600 V, it's also 0.63 A. That's a fine-current motor protection breaker, not a feeder breaker. The fastening method gives you flexibility: screw it down for a fixed install, or snap it on for quick swaps.
That's a good fit for the motor leads you'd typically run to a small motor. No screw-clamp torque worries—just strip and push. Dimensions: 45 mm wide, 106 mm tall, 97 mm deep. That's a compact footprint for a 100 kA interrupting device. Zero clearance forward and backward, so you can pack it tight against the backplane. That covers most indoor panel environments, even unheated warehouses. If your panel sits next to a hot motor or a steam line, you're still fine within that band.
